GABA is a non-essential amino acid. It has been suggested that orally administered GABA increases the amount of Human Growth Hormone, but this is questionable since it is unknown whether GABA can pass the blood-brain barrier. However, orally administered GABA does have effects outside of the central nervous system (e.g. increased muscle tone).

Basically I want to know if GABA is an ingredient in BCAAs... If not where the hell do I get it? If this can fix my anxiety and increase my muscle tone I'm all for it!
